Connecting to Wifi shield from the internet

I have a wifi shield connected to an Arduino Uno. I can connect to my wifi OK but cannot connect to the Uno/shield from the internet. I even tried creating a webpage with a link to the Uno/ shield IP address and that didn’t work either. What do I need to be able to do this?

We need more info on what IP adresses you tried to use to connect to the Wifi shield. Did it work from a computer that is also connected to your wifi network? Please give all IP-adresses of pc on the internet, wifi-shield, subnetmask, gateway, etc.

Not being able to connect to the wifi-shield from the internet is normal if you don’t have port-forwarding setup on your internet-router. Internet packets comming into your router on a specific port need to be forwarded to the specific IP adres of the Wifi-shield. If not, it is simply blocked. Consult de manual of your wifi-router on how to do this.
